WHEEL FOR E moms.

. To all whom it may concern:

Be it known thatI, WILLIAM-D. MoNAULL, a citizen of the United States,and a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a new and useful I1n provement in Wheels for Vehicles, of whichthe following is a s ecification.

My invention re ates to wheels for vehicles and especially forcushioning vehicle wheels without the use of-pneumatic tires.

The invention consists in an improved ex terior elastic tire and a novelcushioning device interposed between the outer and inner Wheel rims. 7

The characteristics and advantages of the invention are hereinafterpointed out in connectionwith the detailed description of the a'c-comanying drawing, which illustrates and exemp ifies structures embodyingthe invention and inwhich F igure 1 is a side elevation of a segment ofi the Wheel embodying the invention. Fig. 2

is a detailed elevation of one of the cushion sections; Fig. 3, a planview of Fig. 2; Fig. 4 is a transverse section on the line ac, Fig. 1.Fig. 5 is a transverse section on the line bb, Fig. 1. Fig. 6 isa detailof the clamping device for the tire. Fig.7 is adetail of a clamp andbuffer. Fig. 8 is a plan view of Fig. 7. Fig. 9 is a plan view of achair. Fig. 10 is an elevation of Fig. 9. Fig. 11 is a modified form ofclamp and buffer.

The outer felly l carries a channeled metal rim 2, in the channel ofwhich is the elastic. tire 3, usually of rubber composition. The

. tire is preferabiy reinforced on its inner surexample of a fastem'ngdevice is shown in Fig. 6, consisting of bolt and' nut 8, engaging ears9, provided on the band.

To further secure the tire and prevent creeping, etc, a number of holesare drilled transversely through the fianges of the channeled rim andtire and through the holes are Specification of Letters Patent.Application area s ruce, 19m. Serial No. 371,005.

The tire maybe endless and in this case, is i I Patented Sept. 29, 1908.

passed rivets 10, which. are headed up at each end to preventdisplacement. The fastening devices provided hold the tire securely inthe rim and absolutely prevent bulging or creeping. The central re-'cess in the tire "afi'or s means for applying the retaining band.7 and"in addition pro vides a double treadwhich effectually resists tendencyto side slip ing and alsoprovides"- other advantages well understood inthe art which have heretofore been attained, in some cases, by therov'ision of two independent tires on the elly.

Lying within the outer felly 1 and separated from it a suitable distanceis inner felly 11, connected by spokes 12-to the hub 13, in the usualmanner. Felly 11 is surrounded by'the metal, band 12 which protrudesbeyond the felly. Between the two fellies is placed a cushioning devicewhich serves, in addition to the tire, to absorb road shocks and drivingstrains, and this device will now be articularly described,

plurality of chairs 14 are laced upon the band 12. These chairs havebases curved. to 'fit the band and end flan es 15 turned up and somewhatinwardly. hese chairs actions 17, shown in detail in Figs. 2 and 3. Thesection's'arecomposed of any suitable elastic or flexible material, suchas rubber or rubber composition. The outer surfaces 18 of the sectionsrest u on the inner surface of the outer felly 1, an the ends 1.6 of thesections have their inner surfaces 19 shaped to conform to theflanges orbooks 15 of the chairs and their outer faces 20 squared off so that,when the sections are placed in the commodate the inner ends 16 ofcushion secchairs, as seen in Fig. '1, the ends of the two I adjacentsectibns fill one of the chairs. The sections are secured to the outerfelly by means ofbolts 21 passing through the felly and nuts 22, plates23 being preferably laced between thenuts and the sections. 11 additionto clamping the sections to the outer felly, bolts 21 may convenientlyserve to secure the channeled rim 2 and thev felly, as shown in Fig. 5'.I

The sections are securedinthe chai rs-by bolts and nuts or othersuitable devices. preferred form of fastening will now be described.

24 are 'clampseach consisting of ga' flat strip 25 having downwardlycurvedends forming flanges 26, aicntral prong 27, and

an outward projection 28 serving as a buffer. The clamps are put inposition as shown in Fig. 4, with the flat strip up ermost and restingon the adjoining ends 0 the Sections, the flanges 26 lying outside thesections and resting upon the bases of the chairs 14. The adjoining endsof the sections are cut away, as shown at 29, Fig. 3, so as toaccommodate the prong 27. The bolts 30, one at each side of each of thejoints, ass through the metal band 12, chair 14, t rough the sections attheir joining, and through the clamps, and all these parts are drawntogether by nuts 31 on the bolts. In 0 eration, when the wheelencounters inequalities in the road surface, the flexible sections 17yield, effectually cushioning the shocks. The driving reaction, weightof the vehicle and road shocks are carried not on] by the sections-atthe top of the wheel but by those at the bottom and sides. In otherwords, the cushioning device acts both under tension and compression. Byvarying the proportions and number of the sections used, the inventionmay be adapted to any character or weight of vehicle, whether horsedrawnor propelled by motor.

, The exterior projections 28 upon clamps 25 serve as buflers'whichencounter the outer felly and prevent excessive relative movement of thetwo fellies. In some cases it is preferred to provide the buffers withrubber or other flexiblec'aps 32 v(Fig. 7), or the buffers may consistof tubular sections of rubber or other suitable material 38 secured tothe clamps by studs 34., as seen in Fig. 11. The structures shown anddescribed exemplify certain forms in which my invention ,may beembodied, but I contemplate many changes in construction which may bemade. without departing'from the spirit of the inventlon. V

. What I claim is: a

1. A cushion wheel for vehicles com rising an inner and an outerfelly,.a plura j ty of chairson one of the fellies and a plurality of 2.In a cushion wheel the combination of' an inner and an outer felly, aplurality of chairs on one of the follies, a plurality of V- shapedflexible cushion sections connected centrally to one of the fellie's andeach havin its ends secured in adjacent chairs, ani clamping devicessecuring the adjacent ends of each pair of the sections in their chair.

. 3. In a cushion wheel the combination of an inner rim, a metal bandthere on protruding at the sides, an outer rim, chairs resting on theband having hooloshaped ends, lexible V-Sl1t)6(l cushion sectionssecured centrally to the outer rim and having their ends resting in thechairs, clamps resting on the adjoining ends of the sections andhavinginwardly extending ends overlapping the sections and resting onthe cha rs, and bolts passing through the clamps, chairs and band andholding the parts in place.

4. In a cushion wheel the combination of an inner rim, a metal bandthereon protrud ing at the sides, an outer rim, chairs resting on theband having hook-shaped ends, flexible V-shaped cushion sections securedccntrally to t e outer run and having their ends resting in the chairs,clamps resting on the ad oining endsof the sections and having inwardlyextending ends overlapping the sections and resting on the chairs, boltspassing through the clamps, chairs and band and holding the parts inplace, and buffersearried by the clamps extending toward the outer rim.
